The effect of maleic anhydride (MA) in the immiscible blends of EVA28 (vinyl acetate content 28%)/ethylene-α-olefin copolymers with 1-butene (EtBC) and 1-octene (EtOC)) comonomers were studied. EVA28/ethylene-α-olefin copolymers are immiscible in the melt and solid state, but mechanical properties are comparable. By adding 1, 2, and 3 phr of MA in the presence of dicumyl peroxide, the morphology of EVA28/EtBC and EVA28/EtOC blends significantly enhanced. In addition, the tensile strength at break and 100 and 300 % of modulus improved, but the elongation at break decreased with EtBC or EtOC. MA incorporated EVA28/ethylene-α-olefin copolymers system is more effective in improving the mechanical properties. Thus, the addition of MA in the blends of EVA28/ethylene-α-olefin copolymers acts not only as a compatibilizer, but also as a reinforcing agent. |
